Small galaxy groups: defining selection criteria
(Asociación Argentina de Astronomía, 2017-10)
El presente trabaja trata de un criterio de selección homogéneo de grupos menores de galaxias definidos como sistemas con al menos dos y hasta seis miembros, compactos y aislados, que favorecen las fusiones entre galaxias. ...
VALES VI: ISM enrichment in star-forming galaxies up to z ∼ 0.2 using 12CO(1–0), 13CO(1–0), and C18O(1–0) line luminosity ratios
(Royal Astronomical Society, 2020)
We present Atacama Large Millimeter/sub-millimeter Array (ALMA) observations towards 27 low-redshift (0.02 < z < 0.2) star-forming galaxies taken from the Valparaíso ALMA/APEX Line Emission Survey. We perform stacking ...
How galaxies populate haloes in very low-density environments: An analysis of the halo occupation distribution in cosmic voids
(EDP Sciences, 2020-06)
Evidence shows properties of dark matter haloes may vary with large-scale environment. By studying the halo occupation distribution in cosmic voids it is possible to obtain useful information that can shed light on the ...

The evolution of the galaxy content of dark matter haloes
(2017)
We use the halo occupation distribution ( HOD) framework to characterize the predictions from two independent galaxy formation models for the galactic content of dark matter haloes and its evolution with redshift. Our ...

Impact of cosmic variance on the galaxy-halo connection for Ly alpha emitters
(IOP Publishing, 2016)
In this paper we study the impact of cosmic variance and observational uncertainties in constraining the mass and occupation fraction, f(occ), of dark matter (DM) halos hosting Ly alpha-emitting galaxies (LAEs) at high ...
